Lighters are a staple in most people's houses. They're used to light fires, candles, cigars, and more - but they can also be pretty fragile. One drop of water can render a lighter useless, which is why it might be a good idea to protect them. This way, you don't have to replace your lighter every few weeks, and you can save yourself some serious money in the long run.
To do this, cover the top of the lighter with baking paper and pour the hot glue on top. When it's dry, you should be able to peel it off, remove the paper, and place the cap back on.
